Specification of Letters Patent.

Application tiled November 20, 1911. Serial No. 661,234.

invented certain new and useful Improve-- ments in Tires, of which the following is a specification.

This invention relates totires for automobile trueks and the like and its novelty consists in the construction and adaptation of the parts, as will be more fully herein after pointed out. Y v

The object of the invention is to produce a strong tire, with a slow wearing tread, sutlicient elasticity for its purpose, easy to make and capable of readily-being put lnto place and removed, and with few parts which are little likely to get out of order and which may be quickly adjusted, repaired or re' newed. a

In the drawings, there is illustrated a tire embodying the invention.

Figure 1 is a side view in miniature of a wheel provided with the tire; Fig. 2 is an edge ,View thereof; Fig. 3 is an enlarged section of a port-ion of the tire taken on a plane at right angles to the axle; Fig. 4 is a transverse section on the plane of the line 1 4 in Fig. 3;' Fig. 5 is an enlarged section on the plane of the line 5-5 in Fig. 1; Fig. 6 is a perspective of one of the cushions;

. Fig. 7 is a perspective ot' one of the t-reads;

Fig. 8 is a perspective of one of the locking pieces, and Fig. 9 is a perspective of a por'- tion ofthe rim, or tread and cushion support.

In the drawings, 10 is the hub of a wheel, 11, 11 are the spokes and 12 is the felly.

Outside of and eneirclinfr the felly is a elly band 13 preferably o steel and outside of that are two rimsl 14, 14, side by side cach having an annular flange 15 on cach side, with a series ot transverse ribs 1Q( each provided with a dovetailed upper section 17 slightly tapering` toward its inner end and projecting radially of the wheel beyond the flanges l5. The ribs 16, telly, felly band, und rim are provided with one or more. apertures 18 adapted to receive bolts. Cushions 2O with flanges l1 along their sides transverse to the riin and made of rubber or other suitable elastic material are adapted to be placed within the several recesses of the rim 14, formed by the annular flanges 15, 15 and the ribs 16, 16. Treads 30 are iliade of steel or other suitable material conforming to the shape ofthe Acushions. 20 over which they. are intended snugly to fit. They are also each provided with flanges 31, 31 adapted to rest upon the flanges 21,21 of t-he cushions'QO when in position. Loek- Patented Aug. 20, 1912.

ing members t0 comprising trough shape I bodies with inwardly turned sides adapted to tit snugly over the dovetailed section 17 of each rib and open at one end and along one side and closed at the bottom, are ada-ptcd to hold the cushions and treads in posi.- tion. The outer surface of t-hese locking members is preferably curved. Each rim 14 is so` arranged that the ribs of one are staggered with respect vto the .ri-bs of the other, so that when the parts are assembled, the treads on each one of thesel tires will be staggered wth respect to those on the iother.

Bolts 50 are adapted to pass through they felly 12, the steel felly band-13,' the rim/14,

the ribs 16 and the locking members lO-t0 hold the parts securely together. f

lVhen the parts are to be assembled a.,

cushion .20 is put into one of the recesses of ion compressed `in order that said tia-nge' 31 shall clear a shoulder 19 formed along the rib 1G below the dovetail. The loc-k member -10 is then slipped into posit-ion trans\'ersely from theouter side of the rim and its sides` embracing the dovetail, se. cui-ely hold the tread 30 and consequently the cushion so in position. It will benotieed that. in the form shown 4each lock member holds two treads, one on each side of the rib. The outer surfaces of these lock members are rounded so as to form a slightly rocking bearing 'for the tread and allow the latter a slight freedom of movement. 'llul closed outer ends of the locking nu-.mbers esclude the dirt. After the parts have been assembled the bolts 50 are put in position and secured by nuts indicated at 51.

The `whcel thus formed has metal treads, simple in shape, readily and cheaply made, held securely in position but with a cushioncd support adapted to take up the shocks il, n

.vorn or broken p artis easilyreplaced and;

one lock or one cushion does not affecttheeiiciency of any other similar member.
